Abstract: 806,702. Magnetic tests. VARIAN ASSOCIATES. July 1, 1955 [July 1, 1954], No. 19140/55. Class 37. [Also in Group XXXVIII] In a device for measuring continuously the earth's magnetic field on a body in rapid motion, two or more magnetometers of the type depending on the pick-up of voltage from nuclei precessing freely in the earth's field after the removal of a local polarizing field at 90 degrees or other angle to the earth's field are operative in turn on the same indicating and recording system. As shown, a constantly driven interrupter 11 controls a relay 12 which during its break periods connects a D.C. source 13 through a damping circuit to the polarizing coils 6 ... 9 of magnetometer 1 and passes on the signals from magnetometer 2 to the indicating and recording system and during its make periods transposes the connections so that magnetometer 1 acts on the indicating and recording system. The Larmor frequency is measured by timing a predetermined number of signal impulses measured by a 13-stage binary counter. The first impulse of a cycle opens a gate 37 to allow 100 kc. pulses from a stable generator 39 to build up a 6-stage binary counter 46 and the 4097th impulse closes the gate. The condition of the 6-stage counter then represents the time taken to receive a fixed number of signal impulses and controls a recorder which may be calibrated in frequency. The signal currents may also be exhibited on an oscilloscope 23. Magnetometer details. The material in container 3, Fig. 3, comprising the precessing nuclei may be water, ethyl alcohol or manganese sulphate. The effect of the polarizing field produced by coils 8, 9 is neutralized as far as remote situations are concerned by coils 6, 7 producing an opposing field. The polarizing field of one magnetometer then does not interfere with operation of the other. Switching arrangements may be provided to enable the polarizing coils to play the part of the pick-up coil.
